Hi ! i always get

1003017: 0xc0 11000000 59 -> 1 1649766000 0
New minute detected after 59 bits
Illegal time zone 1 1
-92: 0xc0 11000000 01 -> 1 1649766001 0
its running on Ubuntu 20.04... i have it on another device running and there it runs fine....

on this device also it shows on startup in -d mode pivot year set to 2022 on the device where it runs fine it shows pivot year set to 2021

Ciao Gerd

From the comments in the source:

 * 17 - 18  Z1,Z2 - time zone
 *       0  0 illegal
 *       0  1 MEZ  (MET)
 *       1  0 MESZ (MED, MET DST)
 *       1  1 illegal

So this looks like mis-received bits.

The pivot year in the year when it was compiled. As DCF77 only transmits the last two digits of the year, it will be used to guess the century.

I know that I have to rethink this strategy in 99 years ;)
